WIP vehicle entity

Adds a new type of vehicle entity that can link to engines/gearboxes/turret drives to control them far more easily and with zero Wiremod components. This requires a LOT more work and polish before it can be released; gearboxes in particular have very little functioning progress so far and need to be able to automatically detect gearbox setups with little to no user input + perform mobility chip duties
